We have a local Guru that likes to smelt down aluminum and build(mill/lathe) things out of what he smelted. http://motorbicycling.com/showthread...=16550&page=15
What is your cc limit over there? <-curious
Yep, I have to change the bore diameter to mach the available rings size, the smaller one that I find are 33mm .. instead the 28mm as original project.
In case of necessity I'll ask to the Guru!
Here the limit is 1 horse power, but don't care... I have a 100 cc 2stroke, that run around 18.000 rpm (kart engine) but it is sooo much :-)
Happy to find other people with same passion!
